Title: Treatment of radioactive waste
Inventor: ISHIOKA HITOSHI
IPC: G21F9/00
Filed: 1988-04-27
Abstract: PURPOSE:To enable taking out solely a small container requiring some mending and putting back it after the mending, by piling up the small containers as units, in underground and by constituting the unit so that each small container may be taken out separately. CONSTITUTION:A small container 8 is made of concrete, a contained mass 10 is a single mass which consists of drums 1 and a space between inner surfaces of the container 8 and the drums 1 which are solidified with concrete and a predetermined gap is placed between the inner surfaces and the mass 8, and also the gap 11 is filled with a stripping material 12. In case that an container 8 taken out from an area where a nuclides leakage is detected, has some faults, a lid of the container 8 is cut off and the mass 10 is lifted up. Because the gap between the mass 10 and the container 8 is filled with the stripping material 12, a part of the material 12 is cut off by lifting-up of the mass 10 and the mass 10 is easily lifted up, therewith the container 8 can be taken out. The mass 10 taken out from the container 8 with some faults, is re-packed into a new concrete container 8 and then is put back to underground to be buried.

Title: Mounting path correcting method
Inventor: SAKAMOTO KAZUHIRO
IPC: H05K13/04
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To minimize the number of the intersections of parts concerning already set mounting paths and to shorten the total length of the mounting paths. SOLUTION: The already set mounting path I1 is inputted to select a route including an intersection maximizing the total sum of distances to the intersection from each mounting part among intersections including intersections formed by optional four mounting parts (S1, S2). When the path successively connecting the plural number of mounting parts forms the intersections, the connecting order of a mounting part nearest to the intersection is changed to remove the intersection (S3, S4). The length of the path concerning the change of the connecting order of the mounting part is compared between before and after the change to detect the shortening degree of the total length of the mounting paths (S5).  Then until the total length of the mounting paths is not shorten any more, the selection of a path and the removing of an intersection are repeated (S6) to output a corrected mounting path 01.

Abstract: PURPOSE:To obtain a piping with a small vibration for a vibration generating force whose frequency is changeable, by providing at least one movable body in a hollow of a basic material furnishing the hollow therein, and providing a means to engage the basic material to the piping. CONSTITUTION:A cylindrical basic material 1 has a hollow 2 inside the body, and movable bodies 3 such as steel balls or the like are provided in the hollow 2. The basic material 1 is composed of a rubber material or the like, and deformed elastically to engage to a piping by its restoring force. When the piping is vibrated, the vibration is transmitted to the basic material 1, and further transmitted to the movable bodies 3. In this case, the basic material 1 and the movable bodies 3 make different operations relatively, frictions and hits are generated at the interfaces between both members, and the movable bodies 3 also hits each other. Since the vibration energy can be absorbed by the hits and the frictions between the movable bodies and the basic material or between the movable bodies each other, an effect to reduce the vibration in a wide frequency band can be obtained.
